Williams (U Arizona) report on behalf of the\nSuper-LOTIS team:\n\nThe 0.6m Super-LOTIS telescope began R-band observations of the error\nregion of GRB080310 (Swift trigger 305288) at 08:38:43 UT, 44 seconds\nafter the start of the burst.  The OT detected by Chornock et al.\n(GCN 7381) and confirmed by Cummings et al. (GCN 7382) is not\napparent in the initial images, but is clearly visible in\nsubsequent images. A stack of the initial 3x10s exposures does not\ndetect the GRB, while subsequent single 20sec exposures do, suggesting\nthat the GRB brightened during the first two minutes.\n\nWe used the USNO-B star at RA=14:40:11.3, Dec==00:10:40.6 (0898-0239265) to\nderive the R magnitude.\n\nThe R-band magnitude of the afterglow in the first image is:\nUT Start   UT End ExpTime  R mag  error\nSingle\n08:40:29  08:41:09 1x20s  17.97 +/- 0.18\n08:41:03  08:41:23 1x20s  16.81 +/- 0.08\nStack\n08:40:29  08:42:37 5x20s  16.91 +/- 0.04\n08:43:24  08:54:27 10x60s 16.98 +/- 0.02\n\nObservations are continuing.
